Be it y.known that w'ejHENRY M.

and CHARLES l?. Br ooxs,.ucitizens of .the. United states, residing at'Pleas'antPlains, in the county `oflndependen cey and State of A1* kansas, have invented a new and usefulNut# Lock, of whicln the following isa specification. -1

This invention relates `to nut locks, and has for its object to improve thefconstruction and increase the eftlciency and ices of this character. x

With these and \other\ objects view tion is better understood, the irvention consists in certain novel features of constructlon Vas hereafter fully described and claimed.

In the accompanying drawings forming a part of this specification andf in which correv sponding oparts are denoted by like designat- `.ing characters, is illustrated the preferred `forni of the ernbc :liinent of the invention capable of carrying the same into practical operation. f l f Inthe drawings z-Figure 1 is a perspective view of the improved device with the loclring latch withdrawn to permit the removal of the nut. Fig. 2 is a sectional view with the locking device in projected position. Fig. 3 is a perspective view enlarged of the spring latch, detached. f

The nut 1L is provided with one or more grooves 11 transversely of its threads, and

the bolt 12 is provided with a longitudinal channel 13, extended laterally as at 111 at the inn-@1 end and deepened into arecess -15 at the outer portion. The channel is also extended across the outer end of the bolt as at 16 and widened laterally and with a depres'- sion 17 spaced iorn the :acess portion.

Aspring latch 18 is seated in the channel 13 and formed w1 th laterally extended inner end 19 to engage the lateral extension 14 of4 the channel, and also extended transversely at the outer end as at 20 for bearing within the widened end extension 16. .The terminal 21 of the'extension 20'is depressed to yieldably. engage the-.depression 17, and theextensi; portion `20 is valso extended laterally into wings 22' to enter the widened portion of the end rer ,ss 1e and form a closure and protection to the recess portion 15. Projecting from the latch leise lug 23 bearing within 4the recess 15.

The laterally extended end 19 of the latch firmly su ports the latter and preventslongitudinall isplacement, and obviates thenc- The device is simple-1n construction, ca be inexpensively manufactured and applied to any size of bolt, or bolts employed for any pur ose.

aving thus described the invention what is claimed is 1. In a nut lock,l a bolt having a longitudinal groove transversely of its threads, and also having a recess in its outer end com- .municating at one end with said groove, the

inner end of said recess being depressed and the outer end of said recess being widened,

a s ring latch engagingsaid groove and with IOO of its threads and deepened at the outer portion and the bolt also having a recess in its outer end in communication with .the channel vfrom the depression.

3. -In a nut lock, the nut having grooves transversely of its threads and the bolt havinga longitudinal channel deepened into arecess at the outer portion, and extended across theend of the bolt, said end extension having a depression spaced from the recess portion, and a s ring latch engaging said channeland exten ed at the outer en d for bearing in the end extension of the channel and with laterally extending wings forming closures to said recess portion and 'Witha terminal depression for yieldably engaging thede ression in said end extension of the hanne .anda -lugeextending I romy said latch' and bearing in said recess portion.

4. In a nut lock, -the nuthaving'grooves I transversely of its threads and the bolt having a longitudinal channel extended laterally at the inner end and deepened into a recess at the outer portion and extended across the end of thebolt, said end extension having a depression s aced from the recess portion, and a springilatch engaging said channel and extended laterally at the inner end to engage the lateral extension of the channel and likewise extended at the outer end for bearing in said end extension of the channel and .with

a terminal depression for yieldably engaging the depression in the same, and with. lateral Wings forming a closure to said recess portion, Aand a lug carried by said latch and bearingin said recess.

I 5. In a .nut lock the nut having grooves ,transversely of its threads .and the bolt h'aving a longitudinal channel exten ded laterally at the inner end, and extended across the lend of the bolt and with a depression spaced from said recess portion, and a spring latch engaging said channel and extended laterally aty the inner end to engage the lateral extension of the channel and likewise extended at the outer end for bearing in said `end extension and with a terminal depression for yieldabl engaging the depression therein.

I ri .testimony that we-claim the foregoing as our own, we 'have hereto aflixed our signatures in the presence of two witnesses.
